Objective: 

This course will enable the students to –

  1. To impart knowledge about not only morphology, structure and development of flowering plants but also at their practical and experimental aspects as they are most sought after areas of modern research.
  2. To enhance the fundamental knowledge about living cells and their systematic up gradation in to the tissue level.
  3. To study the differentiation features of internal structure of the plant body.
  4. To obtain a thorough knowledge about the development cycle in higher plants
